Cephallonia Island in the Ionian Sea is the most seismic active area in Greece. Large number of earthquakes (with magnitude M>6) has been recorded to the region. The last major earthquake (M=6.7) took place in 1983. Since then no other significant earthquakes (M>6) have been recorded.
The area studied within the framework of the multidisciplinary Research Project "Precursory seismic studies in the Broader Area of Cephallonia (Greece)". A large amount of heterogeneous information like: topography, geology, tectonic, morphotectonic, seismology, geodesy (GPS measurements) and satellite images, from different sources, in different format, scale and map projections has been compiled.

Layers in vector and raster format as well as thematic and synthetic maps (Maps 8-12) were produced in a common cartographic system (Hellenic Geodetic System 1987) and a GIS database was developed aiming to Earthquake Emergency Planning.
